My wife shoots a lot with the G1, but not in RAW. She needs relatively simple editing -- PS Elements 8.0 has sufficed. But she does EXTENSIVE cataloging of current and many years' worth of photos -- from scanned to new stuff. We're moving her to an Imac 27" Quad-Core i7 with 8 GB RAM. I'm impressed by Iphoto for cataloging, but suspect Aperture 3.0 would be better for wife's volume of work. 1) Do we Elements for the Mac, or does Aperture's limited processing emulate PSE's? 2) I still shoot primarily in RAW with Canon 10D, not a lot of volume, but higher level of processing. Does this need alter the software equation? Although I use my MacBook Pro, the licensing of Apple software means we can share APERTURE, but I think we'd have to get additional Elements license?
